Tutorial: Create a basic Audio/MIDI plugin, Part 2: Coding your plug-in

Just starting out, today actually, so I am a total noob.

I hope I was able to insert the right code at the right places in the right files, from the “Tutorial: Create a basic Audio/MIDI plugin, Part 2: Coding your plug-in” example.

By the way, it would be helpful to complete noobs like me, if at the end of every example page, there was an actual view or file(s) of every (4) source file in the project, so one could double check everything was inserted in the right places.

Anyways after building in VS 2019, it runs as stand-alone, and as plugin. I insert it on a track in my DAW, then after that a synth, and unless I totally misunderstand something, should every key I hit on my MIDI keyboard, not matter how slow or fast, not be the same velocity to what I set in the slider tutorial. I am asking because it does not seem to do anything!

Is there a zipfile of this tutorial I can download?
